protrusion therefrom; the frame defining a plurality of holes
corresponding to the protrusions, each protrusion latching in one of the
holes.

12. The shielding assembly claimed in claim 11, wherein the frame
includes two opposite sidewalls, the holes defined in the sidewalls.

13. The shielding assembly claimed in claim 12, wherein the frame further
includes two opposite end walls respectively connecting with the
sidewalls, the catch protruding one of the end walls.

15. The shielding assembly claimed in claim 10, wherein the latching
portion is a hollow trapezoid.

16. The shielding assembly claimed in claim 15, wherein the latching
portion further includes two connecting plates respectively protruding
from opposite ends of the resisting plate for connecting the resisting
plate to the main body.

17. The shielding assembly claimed in claim 10, wherein the catches latch
in the latching grooves to further shield the opening.

Description

BACKGROUND

[0001] 1. Technical Field

[0002] This disclosure relates to shielding assemblies, particularly to a
shielding assembly for portable electronic devices.

[0003] 2. Description of Related Art

[0004] A typical portable electronic device, such as a mobile phone,
generally includes a printed circuit board with one or more electrical
components and a shielding assembly mounted to the printed circuit board
for shielding the electrical components. The shielding assembly generally
includes a frame with a plurality of holes and a cover punched to form a
number of bent portions with a number of protrusions formed on the bent
portions. Each protrusion latches in one of the holes to latch the frame
to the cover. However, a number of openings will be defined through the
cover adjacent when the bent portions are formed reducing the
effectiveness of the shielding assembly.

[0005] Therefore, there is a room for improved in the art.

BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Many aspects of the embodiments can be better understood with
reference to the following drawings. The components in the drawings are
not necessarily drawn to scale, the emphasis instead being placed upon
clearly illustrating the principles of the exemplary shielding assembly.
Moreover, in the drawings like reference numerals designate corresponding
parts throughout the several views. Wherever possible, the same reference
numbers are used throughout the drawings to refer to the same or like
elements of an embodiment.

[0007] FIG. 1 is an exploded view of an exemplary embodiment of a
shielding assembly.

[0008] FIG. 2 is another exploded view of the shielding assembly shown in
FIG. 1.

[0009] FIG. 3 is an assembled view of the shielding assembly in FIG. 1.

[0010] FIG. 4 is a cross-sectional view of the shielding assembly shown in
FIG. 3 along the line IV-IV.

DETAILED DESCRIPTION

[0011] Referring to FIGS. 1-4, a shielding assembly 100 includes a frame
10 and a cover 20 latched to the frame 10. The frame 10 may be mounted to
a circuit board of an electronic device (not shown), for accommodating
electrical components of the electronic device. The frame 10 may be
formed by punching a metallic plate and includes two opposite sidewalls
12, two opposite end walls 14 and at least one catch 16, such as two
catches 16. The end walls 14 respectively connect with the sidewalls 12.
Each sidewall 12 further defines a plurality of holes 123. The catches 16
are both protruding from one of the end walls 14, and are substantially
L-shaped (FIG. 4).

[0012] The cover 20 includes a main body 21, a plurality of bent portions
22 protruding from two sides of the main body 21, and at least one
latching portion 24, such as two latching portions 24 positioned near one
end of the main body 21 corresponding to the catches 16. Each bent
portion 22 has a protrusion 222 protruding from an inner surface thereof
corresponding to the holes 123. Each latching portion 24 is a hollow
trapezoid in shape and includes a resisting plate 242 spaced from the
main body 21, two connecting plate 243 respectively protruding from
opposite ends of the resisting plate 242 for connecting the resisting
plate 242 to the main body 21, and a latching groove 244 defined between
the resisting plate 242 and the main body 21. Each catch 16 latches in
one of the latching grooves 244 and resists a corresponding one of the
resisting plates 242 to assist the cover 20 to latch on the frame 10. In
this exemplary embodiment, each latching portion 24 may be made by
punching the main body 21, so that two openings 26 (FIG. 4) are defined
in the main body 21 and aligned with the resisting plates 242. In this
exemplary embodiment, the resisting plates 242 are aligned with and
shield the openings 26 to improve the shielding effect of the shielding
assembly 100. Additionally, the catches 16 latch in the latching grooves
244 to further shield the openings 26 so the shielding affect of the
shielding assembly 100 can be further improved.

[0013] It is to be further understood that even though numerous
characteristics and advantages of the exemplary embodiments have been set
forth in the foregoing description, together with details of structures
and functions of various embodiments, the disclosure is illustrative
only, and changes may be made in detail, especially in matters of shape,
size, and arrangement of parts within the principles of the exemplary
invention to the full extent indicated by the broad general meaning of
the terms in which the appended claims are expressed.
